Hi, I've been in this industry for five years. I hope you enjoyed my blog. Welcome to leave a comment down below.
Interior wall putty powder, tile adhesives, grouting agents, adhesive cement mortars, high-strength grouting materials, etc. can all use hydroxypropyl methylcellulose (HPMC) with a viscosity of 100,000.
The standard of vitrified microbead insulation mortar is higher, 150,000 viscosity hydroxypropyl cellulose or 200,000 viscosity hydroxypropyl cellulose. If you choose 100,000 viscosity hydroxypropyl cellulose, it will easily cause sagging. .
The most important function of cellulose is to retain water, followed by thickening. In interior wall putty powder, as long as it has good water-retention and low viscosity (70,000-80,000), it is also possible. When the viscosity exceeds 100,000, the viscosity has little effect on water retention. It is not necessary to produce interior wall putty powder. Choose a viscosity of 200,000, because if the viscosity is too high, it will be difficult to scrape and the scraper will sink.
High water solubility allows the concrete to fully solidify and continuously increase the bonding strength. At the same time, it can appropriately increase the tensile strength and cutting strength, thus improving the construction effect and improving work efficiency.
In the putty powder, it plays an important role in locking water, bonding and lubrication, avoiding cracks and dehydration caused by too fast water shortage. It also improves the adhesion of the putty powder, reduces the sagging phenomenon during construction, and the construction is relatively silky. slip.
In the gypsum product series, it plays an important role in water retention, thickening, and lubrication. It also has a certain retarding effect, which solves the problem of drum cracking and insufficient original strength during the construction operation process, and can extend the construction time.

Mainly used as an emulsifier, it can increase the compressive strength and cutting strength, improve the surface coating, and increase the adhesion and bonding strength.
The high water solubility eliminates the need to wet or moisten the floor tiles and base in advance, significantly improving their bonding strength. The slurry can be constructed for a long time, is fine and uniform, is easy to construct, and has good wettability.
The addition of HPMC cellulose gives it excellent bonding strength, low shrinkage and high wear resistance, protecting the base material from mechanical damage and avoiding the impact of penetration on the entire building.
Smooth adhesion ensures high-quality fluidity and cement self-leveling capabilities, and the water locking rate is adjusted to enable rapid condensation and reduce cracking and shrinking.
In the architectural coating manufacturing industry, hydroxypropyl methylcellulose can be used as a film-forming agent, emulsifier, demulsifier and thickener to make the film have better wear resistance, leveling, adhesion and improvement The pH of the interfacial tension is used to determine the interfacial tension, and the miscibility effect with solvents is also good. The high water locking characteristics make it have good brushability and flatness.
The viscosity of 150,000 is close to the viscosity of 100,000 and the viscosity of 200,000. It is suitable for both the viscosity of 100,000 and the viscosity of 200,000.
In the application of building decoration materials, especially inorganic thermal insulation mortar, the most important thing is to focus on bonding to increase the strength, making the cement mortar easier to apply, improving work efficiency, and at the same time having anti-sag effect, which is relatively High water-locking properties can extend the working time of cement mortar, improve shrinkage and cracking resistance, improve surface quality, and enhance adhesion.
